The differing conclusions of researchers investigating personality factors in drug users are briefly reviewed. This study, particularly, examines the Minnesota Multiphasic Personality Inventory (MMPI) profiles of self-reported college drug users with the intent of understanding their personalities. The specific research question was: what are the personality patterns, as measured by the MMPI, of college students who seek professional psychological help with their drug usage problems. Five male college students, who had sought help at the Mental Hygiene Clinic of a Student Health Service, comprised the sample. Ranges on the various MMPI scales are included. Each "case" is discussed individually and appropriate data graphs presented. While there are acknowledge limitations in the data, the overall elevation of the profiles is high. The author emphasizes that the MMPI is primarily a diagnostic aid which shows symptomatology and not causality, and cautions that any interpretations must be made in conjunction with other data about the client.
